The apparatus ofthis invention is adapted to be associated with a conventional typewriter for driving the platen of the typewriter in a'manner to position the paper web carried through the typewriter by the platen in predetermined preselected positions having a predetermined sequence and to repeat the sequence -upon a subsequent'portion of the web, the apparatus thereby providing means for typing information upon a continuous web of repeated forms. The apparatus is in the nature of an attachment which can be associated with any conventional typewriter, it'being necessary toonly add a suitable gearing mechanism upon one end of the platen of the type-writer to permit thesame to be drivenby the mechanism of this invention.

Referring to Figures 1 and 2, the typing machine platen control of this invention consists of adriving motor lfl connected to a clutch mecha riism ll through means of a coupling 12. The clutch H has a power output shaft l3 having a gear 14 which-meshes with a gear 15 keyed upon a counter shaft 16. :A line spacing and sheet alength control member I! is mounted vuponthe shaft 18 and 'hasgassociated therewithastop' control 1:8 forregulating the degreenfrotation of the vertical side frames and 2|.

line spacing and sheet length controlmember IT.

The aforementioned mechanism is carried upon a frame consistingof a base member [9 having The side frames 20 and 21 extend in an upwardly direction and are tied together adjacent the top edges thereof by;means of the tie bar 22 which also serves to support a sheet carbon handling device 25. The shaft l6 has a ear 26 mounted upon the end thereof opposite to the gear I5, which gear 26 is associated with the gear'train consisting of the gears 21, 28 and 29. The gear 23is mounted upon the end'of a shaft 30 which is bearinged within the vertical side frames 20 and 2| by means of the bearings 3i and 32 respectively.-

A platen driving mechanism 35 is carried upon the shaft '30 and has suitable gearing associated therewith to be hereinafter described for driving the platen 36 of a typing machine 40.-

The typing machine 40 is of conventional construction consisting of a frame .39 which carries the keyboard M. The frame 39 supports a transversely movable carriage 42 which in turn' supports the platen 36. A type ribbon 43 is provided adjacent the platen 36 in conventional manner and is supported by the spools 44 The usual spacing bar 45 is provided for manually rotating the platen 36 while the paper release for the pressure 'rollers which retain the paper in engagement with the platen 36 is operated by means'of the lever 46 in the conventional manner. The end of the shaft 41 carrying the platen 36 is provided with knurled knobs 4B for manually rotating the platen 36 when desired. 1

Operation of the clutch II is controlled by means of the push buttons 50, 5| and '52 for initiating actuation of theclutch mechanism to' drive the platen operating mechanism for rotating the, platen for line spacing or for advancing or reversing the motion of the paper within the typing machine. The apparatus of this invention is particularly adaptable for feedinga paper web consisting of a plurality of individual webs in adjacent superimposed relationship through'a typing machine for line spacing the web in the machine at predetermined positions 'andfor re peating the identical line spacings as the web is passed through the machine so thattyping can be accomplished upon repeated forms upon identical lines as the continuous web is fed through the machine. The carbon handling device 25 for permitting the making of a plural number of copies upon the individual webs is of the type wherein sheet carbon is used. When passing a continuous web of repeated forms through a typing machine and when using said carbon for duplication of copies, it is necessary that the paper web and carbon shall be simultaneously fed into the machine for typing purposes. After the typing has been completed upon one of the forms the paper Web and the carbon sheets must be backed out of the machine so that the carbon 53 carried upon a bracket 54 and angularly disposed with respect to thesame. 'I'he-uppers-end of the table 53 is provided with a recess 55 into which the rods'extending through a-loop provided in the end of the carbon sheets are adapted to fall when the upper edge of the-carbon sheet is adjacent the recess 55. As long as the rods cooperating with the carbon sheets are in the recess 55 the sheets cannot advance when the The first function which must be capable of being performed is line spacing the forms with respect to the 'type bars of the typing machine in predeterminedpositions and in a proper sequence while advancing the paper web or form through the machine. This is accomplished'by mechanism which will be hereinafter more fully described. The second function occurs after the form face has been completely typed, which function reverses the direction of movement of the paper web and the carbon sheets held between the adjacent sheets of the web to cause the paper. web and the carbon sheets to move upwardly along the table 53 of the carbon handling device 25 so that the edges of the carbon sheet holding bars will engage the recess 55. The third function to be accomplished by the platen controlling mechanism is to again advancethe paper web through the machine to a position that the bottom edge of the form which was just typed will be adjacent, a tear off blade so that the forms may be removed from the continuous web.

A further function of the apparatus consists of permitting the line-spacing control member to return to an initial predetermined position for initiating forward advancement of another form through the typing machine. This last function is used when forms of a length shorter than'the longest form capable of being handled by the without interfering with the sequence of the opermachine are being used. A fifth function is to ing machine to permit erasure of typographical errors and to return the platen to the proper line ation of the line spacing mechanism. 1

,The clutch ll controls the power connection between the motor I!) and the operating mechanism for driving the platen 36. As shown in Figures 19 and 20 the clutch ll consists of a casing 6| having a hollow interior 62 withinwhich theclutch mechanism is positioned The lower portion of the casing 6| is open at the top thereof, which open portion is closed by means of a cover 63. A drive shaft 64 extends transversely of the casing BI and is suitably bearinged inthe walls of the casing. A worm. 65 is suitablysecured to the drive shaft 64 and engages a worm wheel 66 pinned to a'shaft 61 which extends longitudinally of the casing 6|. The shaft 61 is provided with collars 68 for positioning the same 4 within the casing 6|. Aspur gear 69 is pinned to the shaft 61 for integral rotation therewith. A clutch 10 has one element H thereof pinned .to

the shaft. 61 while the other element 12 of the clutch 10 is slidably positioned upon the shaft 61.

The clutch element H is provided with a;tooth l3, while the clutch element 12 is provided with a tooth I4, which teeth are adapted to cooperate so that'the clutch element I2 is driven by the clutch element lI when the teeth 73 and I4 are in engagement thereby driving the gear I5. The gear I5 is in meshing relationship with a gear #6 which is pinned to the output shaft I3 of the clutch II.

An annular groove I1 is provided in, the unit assembly consisting of the gear I5 and the clutch element I2 within which a shifting yoke I8 is positioned. The shifting yoke I8 is carried by a collar I9 pinned upon a shaft 80 adapted to reciprocate longitudinally in order to shift the tooth I2 into cooperating relationship with the tooth 73. A'spring 8! is positioned between the collar I9 and a wall of the casing 6| to urge the collar I9 in a rightward direction (as viewed in Figure 19). The end of the rod 80 is provided with a roller 82 which engages a T-bar 03 mounted upon a shaft 84 in the wall of the casing M.

The T-bar 83 is provided with the cam surface 85 against which the roller 82 is adapted to be positioned. When the T-bar 83 is oscillated by the shaft 84 in the direction of the arrow on the T'-bar 83 the cam surface 85 will permit the rod 80 to reciprocate and thus engage the clutch.

The gear 69 of the clutch II meshes with a gear 86 (see Figure 20) which is pinned to a shaft positioned in the same horizontal plane with the haft 61. The gear 86 drives the shaft associated therewith in a reverse direction to the shaft 61 so that the clutch elements 81 and 88 of the clutch 89 will rotate in a reverse direction with respect to the clutch 10. The gear 90 is. integral with the clutch element 88 in the same manner as the gear I5 is integral with the clutch element I2. The gear 90 is in meshing relationship withthe gear I6 and thus with the output shaft I3. The clutch 89 is shifted by means of a shifting fork carried by the collar 9| actuated by a rod 92 carryinga roller 93 which is in engagement with the T-bar 83 on the end opposite to the point of engagement of the roller 82 with the T-bar 83. The cam surface 85 extends completely across the T-bar 83 and thus in engagement 1 with the roller 93.

v The clutch mechanism herein described consists of parts having relatively lightweight and since the clutch teeth of the clutching mechanisms I and 89 arein very close relationshipclutch mechanism herein described is shifted by means of the push button controls and 52 in a manner which will be hereinafter described.

The output shaft I3 of the clutch II transmits power from the motor I0 to the gear I4 which is the first of a series of gears, I5, 26, 21 28 and 29, comprising a gear train to the shaft 30 whereby the shaft 30 is rotated by means of the power derived from the motor I0. The gears 2'! and 28 are suitably bearinged upon the vertical side frame; while the gears 29 and 26 are carried upon their respective shafts and I6 (see Figure 1). I

A power transmitting mechanism is carried upon the shaft 30 and is adapted to transmit the rotary motion of theshaft 30 to the platen 36. This mechanism (see Figure 21) consists of a housing 94 journaled upon the shaft 30 and adapted to reciprocate upon the shaft in unison Journaled upon the platen shaft 41.

with the shifting of the carriage 42 of the typing machine 40.. The housing 94 has an extension 95 within which an extension 96 from a housing 91 is adapted to telescope. The housing 91 is The telescoping extensions 95 and 96 provide means for transmitting the shifting motion of the carriage 42 of the typing machine 40 to-the platen driving mechanism 35. A hollow shaft 98 is journaled within the housing 94 and has a bevel ear 99 suitably secured thereto. The interior of the hollow shaft 98 is provided with a plurality of rollers I00 which-engage a keyway I 0| provided in the shaft 30. The keyway IOI extends substantially the full length of the shaft 30 to permit the platen driving mechanism 35 to traverse the typing machine '40 the same distance as the carriage 42 thereof. The rotation of the shaft 30 is thus imparted to the bevel gear 99 through the rollers I00 and the shaft 98.

A shaft I02 is positioned axially within the extension 95 of the housing 94 and has a bevel gear I03 suitably pinned on one end thereof. A bevel gear I03 is in meshing relationship with respect to the gear 99. The shaft I02 is bearinged in a ball bearing I04 positioned, within the extension 95., The shaft I02 cooperates with the hollow shaft I06 coaxial with the extension 96 andbearinged therein by means of the ball bearing I01. The shaft I06 is provided with a recess I08 which engages a keyway I09 in the shaft I02 to provide a splined joint between the shafts I06 and I02. The opposite end of the shaft I06 carries a bevel gear IIO suitably secured to the shaft I06 which is in meshing relationship with a bevel gear III sccured'to the platen shaft 41.

As previously'mentioned the carbon handling device 25 is floated upon the tie bar 22 by suitable anti-friction members. Specifically, th carbon handling device 25 is carried upon a frame H5: which has a pair of rollers H6 and III adaptedto rest upon the upper face of the tie bar -22.' A roller II9 engages the lower. face of the tie bar 22 and thereby provides a 13-point suspension for the frame H5. The frame II5 extend downwardly behind the platen operating mechanism and has a roller 9 positioned on .the loweredgethereof. The roller I I9 engages a'channel I20 suitably secured to'the vertical side frame 2I and the clutch II -(as shown in Figure 1). The roller II9 cooperating with the channel I20 provides means to prevent rotation of the framel I5 upon the tie bar 22. The carbon handling device 25 is carried upon the frame I I5 by the bracket 54 as previously described.

The frame I I5 is free to reciprocate upon the tie bar 22. This frame, however, is interconnected with the carriage 42 of the typing machine 40 through means of the platen driving mechanism 35. A rod I22 is secured to the frame I-I5=by means of shoulders I23. The rod I22 extends through an opening in the bracket I2I extending from the platen driving mechanism 35. A helical spring I24 is positioned between the shoulder I23 and a collar I25 slidably positioned upon'the rod I22. .A helical spring I26 is positioned between the bracket I2I and a washer I21 'secured'upon the end of the rod I22. The springs I324 and I26 provide a resilient shock absorbing system between thecarriage 42 of the typing mamass of the frameI .and the'carbon handling device carried thereby. The carbon handling device 25 is thus carried transversely with the carriage'42 of the typing machine 40 ina smooth floatin motion rather than in a jerky motion developed by the carriage 42. I v I In order to control the rotation of the platen 36 and thus to control the lin spacing for typing upontheweb 60, a control mechanism is interpositioned between'jtheclutch II and the shaft 30. The controlme'chanism also is adapted to control the forward advancement of the paper web through the machine to a predetermined tear off linefso that repeated forms on a continuous web can be removed. The control mechanism is also constructed and arranged to permit reversal or backing out of the paper web in order to position the carbon sheets upon the carbon handling device in a manner to prevent a. forward motion of the carbon sheet when the paper web is advanced to the position wherein the form which has just been completed is adjacent the tear off knife. v

The controlmechanism consists of thev line spacing and sheet length controlling member I1. This'member' I1 is in the 'form of a gear to the extent that the periphery thereof is provided with a series of adjacent parallel slot I28 extending transversely of the member. The member I1 being secured upon the'shaft I 6 is rotated with the shaft I6 whenever the same is driven by the clutch. v f A rocker arm I 30.is pivoted upon a pin I 3| secured within 'a stud I32 mounted upon the casing 6| of the clutch II. (see Figures 14 and 15). A pawl I33is pivoted upon a pin I34 upon the upper end of the rocker arm I while a pawl I35 is' pivoted on a pin l36up'on the lower end of the rocker arm I30. Helical springs I31 provide a balanced system maintaining the'pawl I33 in a predetermined position, while springs I38 provide a balanced spring system for maintaining the pawl I35 in a predetermined position. Set screws I39 are provided in the rocker arm I 30for adjusting the tension of the springs I31and I38 described and is retained in engagement with that surface by means of 'a torsion spring I 6|. Thearm I59 in cooperation with the cam gplate I44 provides means for developing a snap acting movement in the operating mechanism in arnanner hereinafter described. I V

A control actuating mechanism is provided for shifting the pawl I33, transversely with respect to the periphery of the line spacing member I1 in order to bring the pawl I33 intoalignment with the median line of, the transverse dimension of the member I1 for reasons which will be hereinafter explained. This mechanism consists of a vertically. positioned rod I62 rotatably mounted within suitable'bracket's I63 extending from the side wall of the clutch I I (see Figure 24); Opposite ends of the rod I62 are provided with arms I64 and'I65which form a bellcrank lever. The

' arm I64 engages a rod I66 slidably positioned withinthe studs|32 and I61 extending from the casing of the clutch I I. The opposite end of the rod I66 engages the rocker arm I30 to transve'rsely move the "same with respect to the line spacing member I1. The pin I42 extending'from the secondary lever I4I permits the transverse shifting'ofthe' rocker arm "I30 without losing the driving connection between the rocker arm I30 and the actuating lever'system extending from thecamplate|44. v

The arm I65 engages the'end of a reciprocating rod I68 positioned within the casing I69 provided for the control actuating buttons 50, 5Ifand 52. Atc'ontrol actuating button 50 is positioned upon theend of the rod I68. Y I

A helical spring I10 is positioned between the rocker arm I30 and an enlarged head "I pro- 'vided on the pivot pin I3 I (see Figure 15) whereby the rocker arm I30 is normally maintained to provide the necessary balance therebetween.

The pawls I33 and I35 are adapted to cooperate with keys 0 positioned in the slots. I28 upon the line spacing control member I1 for actuatingv the rocker arm I30 in a manner hereinafter described.

A secondary lever I 4| is pivotally carried upon the pin I3I and is provided with a pin I42 which extends into a hole I43 in the rocker armI'30. The secondary lever I4I isconnected by means of. the link 2I2 to a cam plate I44 pivoted at I45.

The cam plate I 44 is connected to a link I46 which is secured to a rod I41 by means of an interconneoting link I48. The rod I41 has a link I49 sethe sharp edges I and I 56 from which cam surfaces I51 and I58 extend in an opposite direction to thecamsurface I54. An arm, I59 is pivotally mounted upon-a pin I60 extending from the easing 6 I. of the clutch II. The arm I 59 has a roller I29 which engages the cam'surface heretofore in the position shown in Figure 15-a inSt the; end of' the rod I66. The rod I66 is prevented from movement in a leftward direction as 'viewed in Figure 24 by means of a stop pin I12provided on the arm I68 which engages a transverse par,- t ition I18 provided in the casing I69. Thestop button centrolsjl and52 are mounted upon a common U-shaped lever I13 which is pivoted at I14 to the casing I69. A pair of ears I15 extendfrointhe arm I13 and are adapted to engage the under side of a'leaf spring I16 op posite ends of which are secured to the casing" I69. The leaf spring I16 centralizes the position of the control'buttons 5| and 52 (as'shown in Figure 25'), The stop button control 50 ex tends through the frontyface of the casing I69 for operationin a straight reciprocatory motion. The arm I13 is provided with a cylindrical pin Ipreviously-mentioned for engaging the recess I52 in the arm I50.';'The' arm I 50 rests upon a set screw I11 threaded through a partition I18 within the casing I69. The recess I52 is provided with a V- shaped forward and'rear wall, I19 and I respectivelyi The sharp edge of the v when in'normal positionias shown in Figure 25) is arranged. to be at or sl ightly below the axial center of 'thepin I53. Whenone of the push buttons 5| or 52"has beenpressedto pivot the arm I13 about the pivot I14 the axial centers of thepin I5 3' dropsfibelow the sharp edge of the V-'shaped walls 1119 and I80 whereby'any excess movement-which is imparted to therod I50 through any accidental means would cause the rod 'I50,,t o rise over the pin I53 to prevent jamming of the operating mechanism. The set screw I11 is provided forjadjusting the horizontal relationship between the sharp edge of the -V- shaped walls H9 and I80. with respect to the axial center ofthe'pin I53;

The motor Ill drives the clutch mechanism I I through means of a friction coupling I85. This coupling I85 (see Figure30lconsists1of a. flywheel I8Band receives the. end of the motor shaft [90. The iorwardfaceof the flywheel. [86 is provided witha. boss I'9If which has a finished surface thereon'to engage a leatherkey ISZpositioned within a slot. [53 'provided'in a coupling member I84 iour-naled uponlthe'. motor shaft I90. The coupling member lfllissecured to the motor shaft I90 by means of the set screw l95. The face of the coupling member IN is provided with a. cylindricairecess I96 whichv is just slightly larger in diameter. than the boss I'9I on the face of the flywheel I80. The leather key I92; is provided with a hole I91. through which the motor shaft I80 extends.

The coupling member I 94 is. advanced toward the face of the boss ISI on the flywheel I86 until the face of. the leather key I91 is in tight surface engagement with thesurface of the. boss I9I. The set screw I85. is then tightened upon the motor shaft. 190' to secure the coupling. member I94 imposition. .This. arrangement. provides a frictiondr-ive from the motor to the clutch which permits slippage between the motor drive and the clutch should the clutchbecome jammed.

Thev clutch II and. the motor, I are secured to acommonmounting. plate I98. Theclutch II is provided. with three extending legs I99 which are secured. to the mountingplatelsaby means. of the: screws 200,-. Themotor. I0. issupported upon themounting plate'by means oi the rubber grommets orblocks. Two.- of. these support members are provided for positioning the motor upon .themounting plate I98. A rubher grommet 202 is provided adjacent the bottom surfaceoi the. mounting plateI98- and. a screw 203 extends through. the rubber mounting menibers202 andZIII intothreaded engagement with the motor I0.

v The rubber mounting members 201. and 202 provide a certain amount of resiliency to the mounting means so thatthe shaft I90 of the motor can beproperly aligned with the. bore I89 provided in theflywheel I86. By eitherftightening. or loosening the. screws 203 the motor shaft. I can be. shifted. vertically or angularly with respect to the vertical, limited only by the degree of compressibility by the rubber mounting members 2M and 202. Such amounting provides a very accurate method oi. aligning the motor shaft I90 with the driving. shaft-.04.

The friction drive device. justdescribed provides a safety feature between themotor I0- and the clutch I I. An additionalsaiety device is provided between the clutch H and thegear t5. This device (see Figure 1) consists ota friction disc 204 retained in engagement with the. gear 15 by means of the clutch plate 205 and a lear spring 200.

element on both sides thereof to protect th delibate operating mechanism.

In Figures, 3 to 13 inclusive there is shown a diagrammatic and simplified arrangement of the operating mechanism of this invention showing certain of the elements in various positions in their operation. 'By referring to these figures in the following description the full operation of the device will becomeapparent. I

As previously'mentionecl thecontrolling device ofthis invention is particularly adaptable. for controlling the operation of the platen of a type-,

writer for advancing a continuous web of repeated forms through the typewriter in amanner that preselected lines upon the forms can be automatically brought into alignment with the typing 'bars. the apparatus being constructed and ar:

ranged so that the selected lines of the repeated forms will be brought intoalignment with the typing bars in a selected sequence, the sequence being repeated for each of the forms as typing proceeds upon the various forms. In addition, the apparatusv is adapted to reverse the motion of continuous web forms topermit release of sheet carbon and to again advance the continuous web to bring the bottom edgeof the typed form adjacent a tear off blade 2 I0 so that the typed form can be. torn, from the continuous web. .All of these operations are automatically carried out atterbeing initiated by means of push button controls.

In order to set the typewriter platen controlling device for typing a particular form and particular lines on that form the line spacing keys I40 are positioned within the teeth or grooves I28v of thecontrol wheel I 'I. The line spacing keys I are positioned on the lefthand side of the wheel I! (as viewed in Figure 3), key I40a representing thelast line spacing key for the form.. Since. sheetcarbon is used between. the adjacent forms of the continuous web the paper web :must be reversed in. its motion to permit release .of the carbon from between the forms. A key [40b is positioned upon the right hand side of the wheel. ll andgis adapted to engage. the lower pawl I35 to stop the reversing motion when the carbon has been-movedupon the carbon hane dling device 25 to a. position that it. is free from the paper webs. The paper web must then be advanced to permitthe bottomedge of the form tobe brought, adjacent to the tear off knife 2l0. A tear oflf key l illcis positioned in the'center. line of. the periphery of thewheel I! and is adapted to engage the upper. pawl I33 to .stop the mechanismwhen the bottom edge of the form is adja-.

centthe tear off knife 2| 0.. The keys I40, Ulla, [40b and I40c as set up in Figure 3, are positioned in. their proper relative positions for automatically controlling the movement of the platen 0t thetyping machine 40 for properly moving the paper web therein.

Figures 4 to 8 diagrammatically represent the respective operations produced by the typewriter controlling device. Figure 4 shows the control wheel. I! in position to start a typing'operation upon a form. The uppermost key I40 has just actuated the pawl I33 to stop the paper web at the heading line or first line, of typing upon the form. The electric motor I0 is rotating continuously. during the operationof the machine, the driving motion being interrupted by' the clutch I I.

To advance the web .60 to the next line of typing the advance button Si is pressed downwardly thereby pivoting the arm I13 about. the pivot pin I14 to shift the bar [50 in a forwarddirection (as viewed in Figure 3). Shifting" of this bar I50 transmits rotary motion to the shaft I41 to cause the links I 46 and I48 to push upwardlyupon the cam plate, I44 and thus rotate the shaft 84 of the clutch I I.

When the. cam plate I is rotated'in an 'upwardly directiontwo simultaneous operations occur. The T-bar 83 off the clutch II is rotated to permit the clutch control bar to advance and thereby cause engagement of the clutching'mechanism to drive the gear I4 and thus the shaft I6 and the control wheel II. This driving motion is transmitted through the geartrain, 26, 21, I 28 and 29, to the driving rod 'and thus to the platen driving mechanism for rotating the platen to advance the paper web 60.

The second operation initiated by the rotation of the cam plate I44 consists of transmitting motion through the link system from the cam plate J44 to the rocker arm I30 to cause the rocker 144. Movement of the push button 5| rotates the cam plate I44 to bring the edge I55 of the cam surface I54 adjacent the roller I29 whereby the roller I29 throws the cam plate I44 over center and rides upon the face I57. The spring I6I provides the force required for the snap acting operation. Y

When the pawl I33 is brought into adjacent relationship with respect to the whee1 I! the forr ward edge of the pawl I33 is positioned ahead of the next successive key I40. The clutch II has been engaged whereby the wheel is being driven in a forward direction represented by the arrow lever system between the rocker arm and the cam plate I44 to move the cam plate in a forward direction (as viewed in Figure 3) until the roller I29 is adjacent the edge I55 of the cam surface I54. plate I44 then causes the roller I29 to engage the declining surface I54 and rapidly move the cam plate to open the clutch mechanism and complete the returning movement .of the rocker arm I30. The position of the'rocker arm I30 with respect to the key I is shown in Figure 11.

When the pawl I33 is again advanced by the rocker arm I30 due to movement of the push button 5! the edge of the pawl I33 may strike the upper edge of the key I40 (as shown in Figure 12). The balancing springs I31 permit the pawl to move in a rearward direction until the key I40 is cleared, the lower spring I31 then moving the pawl into the position shown in Figure'13 so that the next subsequent key I40 may engage the pawl I33 to return the rocker arm I 30 as heretofore described.

Each time the operator of the typing ma'ch'ine desires to line space the machine the push button M is pressed and the function heretofore described produced, each of the keys I40 halting'the forward advancement of the paper Web at the proper line for typing. v

Since sheet carbon is used between the adjacent sheets of the Web 00 it is now necessaryto reverse the motion of the paper web to permit release of the carbon sheets. The reverse button 52 is now pressed to cause the bar I50 to move in a rearward direction and therefore transfer motion to the cam plate I44 to rotate the same downwardly and thus permit the control bar 92 of the clutch II to permit engagement of the clutching mechanism 89 wherebythe gear I4 wil1 beirotated in a reverse direction and thus reverse rotation will be transmitted to the platen through the power Slight additional movement of the cam 'verse rotation of the platen will continue until the carbon reverse key I40 strikes the lower pawl I35-which functions in the same manner a the pawl I33 to" halt rotation of the control wheel I! and the platen 36 of the typing machine. The carbon sheets, will now be in position to be retained by thecarbon handling device to permit the adjacent sheets of the paper web to be advanced through the typing machine to a position that the lower edge of the form just typed will be adjacent the tear olf knife 2 I0.

To control the position of the paper web in this operation the push buttons 50 and 5I are simultaneously depressed. The push button 5| initiates the advancing motion of the paper web in the manner heretofore described. Rearward motion f of the push button 50 causes the rocker arm I30 to be shifted to the right (as viewed in Figure 3- and as shown in position in Figure 18) to bring the pawl I33 into alignment with the center line of the wheel H. The forward motion of the wheel I I continues until the tear off key I400 strikes the pawl I33 and causes disengagement of. the clutch II in the manner heretofore described.

It will of course be understood that the. position of the tear off key with respect to the carbon reverse key is such that the tear off key will not be positioned between the pawls I 33 and I 35 when the carbon reverse key I401) is adjacent thepawl I35. If the tear off key I400 should be positioned between the pawls the machine would not advance to the tear off line but rather would advance by a short distance and the tear off key I400 would stop the machine.

After the control wheel I] has been rotated to bring the tear off key I400 adjacent the pawl I33 to stop the advancement of the paper web through the machine the top edge of the next successive form will be adjacent the tear ofi knife 2I0 the first key I40 representing the top edge of the form sheet. Theform sheet will be in proper position to permit indexing of the web to the first typing line represented by the second key I40, but thecontrol wheel I 'I will not be in proper position if a short form is beingused in the machine. To bring the control wheel I! into the proper position the paper release bar 46 ofithe typing ma chine49 is moved manually to release the pressure rollers from the paper. web passing under the platen 36. The platen 36 can now be rotated without advancing the paper web through the machine, The advance button 5| is now depressedto rotate the control wheel I! until the first key I40 strikes the pawl I33 to stop the machine. This "operation resets the wheel I! so that subsequent line. spacing will be accomplished in the samesequence as upon the form which was just removed from the'machine.

.It is of course understood that after the wheel IT has been preset to its initial starting position that the carbon sheets will be released from the carbon handling device 25 so that they can advance through-the machine with the paper web 60 when it is advanced to the first typing line by the first indexing operation.
